Tachyon cannon

Perhaps the most powerful weapon available to humankind, the tachyon cannon is a satmet that causes a specific tachyon interference along a line of effect. Namely, the inversion of charge, causing a significant quantity of matter in a localized region of space to become antimatter.

The mobius patterns are defense against this effect, and hadronium is somewhat resistant. Regalia are, of course, unaffected, as are delta-grade beings such as astrum parvulus.
